Description

The present invention relates to a prefabricated lattice (grating), and more specifically, indoors as well as sewage outlets and drainage outlets installed on the floor of a restaurant kitchen, a bathhouse, a pool, etc. that use a large amount of water. It relates to a lightweight prefabricated lattice to be used for outlets installed to supply cold / hot air through walls and ceilings for cooling / heating.

Conventionally, in Patent Document 1, a strut in which non-slip unevenness is formed on the upper surface and a rib in which projecting blades are integrally formed on both sides of a tubular body are manufactured by an extrusion method, and a press or a puncher is formed on the vertical bone of the strut. A hole through which the tubular body of the rib can be penetrated and a slot through which the protruding blade of the rib can pass are formed together on the left and right sides of the hole, and the columns are arranged at regular intervals. Using a press or puncher so that it is in the same position as the vertical bone of the rib, a cutting groove is formed in the protruding wing of the rib so that the width is the same as the thickness of the vertical bone of the strut, and then the strut is worked. The tubular body of the rib is inserted into the hole formed in the vertical bone of each strut while being sandwiched and fixed between the jigs assembled on the table at regular intervals, but the rib is separated. Align the position of the rib cutting groove from the underside with the position of the vertical bone of the strut so that the protruding wing is horizontally passing through the slot of the strut, and rotate the rib 90 ° to the vertical bone of the strut. The protruding wings of the ribs separated between them are inserted and engaged while standing vertically, and the columns and ribs are integrally formed by a lattice structure to reinforce the columns and ribs that are integrated with each other. Described how to manufacture a prefabricated lattice in which the ends of the columns located at the four corners of the reinforcing frame and the reinforcing frame are spot-welded at only four places after being settled inside the frame so that the columns do not separate from the reinforcing frame. ing.

However, these prefabricated lattices are formed by cutting the vertical position of the strut at the same position as the vertical position of the strut with the protruding wings on the left and right of the rib so that the vertical bone is sandwiched and meshed with the cutting groove formed by cutting the same position as the thickness of each vertical bone. Since the support and the reinforcing frame are assembled, the depth of the cutting groove where the vertical bone is inserted and meshed becomes shallow, so if it is made lightweight, it will be caused by pressure, vibration, impact, etc. that will be generated every time the user passes. The combined load is concentrated by the vertical bone on the bottom of each cutting groove, resulting in deformation such as easy bending of the relevant part of the rib, or the vertical bone is severely disengaged from the cutting groove, of course. In some cases, there is a problem that cracks or the like occur and the life is shortened.

In addition, since the vertical bone and the cutting groove are assembled in a state where they are in surface contact with each other, metal noise due to friction is generated between the contact surfaces each time vibration or impact is applied, and the contact surface is easily made. There is also the problem that it is worn and loosened in the assembled state, further shortening the life.

In addition, with the columns and ribs settled in the reinforcement frame, the ends of the columns located at the four corners of the reinforcement frame and the four reinforcement frames are spot welded to fix the columns so that they do not separate from the reinforcement frame. Therefore, since it is necessary to separately prepare an expensive spot welder for welding work, there is a problem that not only economic efficiency but also workability is significantly reduced.

In addition, when spot welding the tip of the support and the four reinforcement frames in order to fix the support so that it does not separate from the reinforcement frame, the support can be easily separated from the reinforcement frame even if vibration or impact is applied. Must be welded tightly so that they are integrated, and can be used when any of the columns and ribs are deformed or cracked and need to be replaced. The removal and installation of the stanchions and ribs is also very complicated, time consuming and related costs, as the person has to disassemble, separate and replace the four tightly welded parts and fix them again by spot welding. There are also problems such as the cost.

8 is a perspective view showing a state in which the main bar of FIGS. 3a and 3b and the crossbar of FIGS. 4a and 4b are assembled, and FIGS. 9a and 9b are respectively assembled with the main bar of FIG. FIG. 10 is a perspective view showing a state in which the fixed bars of FIGS. 5a and 5b are assembled at both ends of the crossbar and a state in which the fixing bars of FIGS. 5a and 5b are assembled. Is a side view showing a part of the above, and FIG. 11 is a side view showing an example of a state in which the prefabricated lattice of FIG. 10 is attached.

When assembling the main bar (10), the crossbar (20), the fixed bar (30), and the frame (40) to form a grid, first, a large number of the main bars cut to the same length are mentioned. Use jigs provided on the workbench at regular intervals in the front and back so that they can be placed in parallel.

When settled in this way, the joint holes (15) and through holes (16) drilled in the main bar (10) at regular intervals are all located on the same line so as to coincide with each other. At this time, all the through holes (16) are made horizontal.

In such a state, the length is obtained by adding two of the intervals (s') between the main bars to the entire front-rear interval (s) in which the main bars (10) are mounted at regular intervals. The bundling piece (21) penetrates the through hole (16) and is bonded to each coupling hole (15) through the crossbar (20) cut so as to be made (l).

The binding grooves (22) formed in the binding pieces (21) of the crossbar (20) at regular intervals are located in the binding holes (15) formed in the main bar (10). Then, the crossbar is rotated by 90 ° so that the binding groove portion faces upward, and the front and back surfaces of the peripheral edges of the joint holes are sandwiched between the front and rear surfaces (221) and (222) and mesh with each other. To be united.

At this time, the length of the crossbar (20) is set to 2 of the distance (s') between the main bars and the total front-rear distance (s) in which the main bar (10) is mounted at regular intervals. Since the length (l) is the sum of the two intervals, the front and rear ends (20a) and (20b) of the crossbar penetrate the front and rear main bars in the main bar. Each one of the intervals between the main bars will be exposed before and after the front and rear main bars.

In such a state, the two fixed bars (30) cut in the same length as the main bar (10) are crossed in the longitudinal direction across each end of the crossbar (20), respectively, before and after. While keeping them in close contact with each other, the screw holes (38) are aligned with the screw fasteners (23) formed at the front and rear ends (20a) and (20b) of the crossbar, and the binding screws (24) are fastened respectively. Fix it.

Prevent the phenomenon that the binding screw is released at all.

Therefore, the main bar (10) and the crossbar (20) are firmly united and fixed together with the fixing bar (30) to form one body assembly (A), and at this time, the fixing is performed. The spacing between the main bars before and after the bar is the same as the spacing between the main bars.

When the assembly (A) formed in this way is attached to the frame (40), the fixed pieces (414) of the front and rear members (41) and (41') are spaced at regular intervals as needed. The screw fastening hole (43) may be first drilled, and the fixing screw may be fastened to the bottom through the screw fastening hole to fix the frame.

After that, the fixing plate (32) to which the elastic member (39) is attached is located below each upper piece portion (411) of the front and rear members (41) and (41'), and is located below the elastic member (39'). ) Are connected to the lower plate (34) and the like, and the assembly (A) is inserted into the frame (40) so as to be located above the lower piece portion (413) of the front and rear members.

When inserted in this way, the upper end portion of the elastic member (39) is crimped to the lower surface of each upper piece portion (411), and the curved lower portion of the elastic member (39') is the lower piece portion (413). Since it is bonded to the upper surface so as to be crimped, the assembly (A) is stably mounted on the frame (40) to form one grid.

When installing the grid manufactured in this way, the front and rear members (41) and (41') are formed on the upper part of the front and rear inner surfaces of the sewage and drainage port (l) installed on the floor, respectively. 2) When each of (2') is settled, the grid is installed so as to cross the upper part of the drainage port.

In such a state, if the fixing screw is fastened to the bottom through the screw fastening hole (43) as needed, the grid is firmly fixed and installed at the drain port.

The lattice according to the present invention installed and used in this way is not only very easy and easy to assemble and separate, but also prevents shortening of the life even if it is manufactured lightweight, and at the same time, the manufacturing cost and the maintenance cost are also reduced. It will also have the effect of being significantly reduced.
